Leaking pipe repair from inside the pipe.

WA-internal pipe repair clamps are a very low profile leak repair expansion seals for large pipes. The clamps do not affect optimum water flow through the pipe. Safe working pressure up to 240 psi / 16 bar. Applications for water, gas and petrochemical fluids.

Prevents infiltration into the utility system. Special tools for installation are not required.


The expanding clamps are full width passivated 316L stainless steel pressure plates and rubberized seals.

Special tools are not required. The clamp can be used on various material pipes.

WA-internal pipe leak repair clamps stop leaks in larger pipe diameters, 20 inch diameter and larger. The seal units are standard 200 mm wide.
